The question is.
Consider the function f(x)=sqrt(x)/sin(x),0<x<pi
Show that the x coordinate of the minimum point on the curve y=f(x) satisfies the equation tan x=2x
the question is worth 5 marks/points

Where did you get this one? The problem looks okay but once you get the minimum point the rest is rather ridiculous.

How do you find the (relative) minimum of any function? (Hint, hint: Remember the endpoints of your interval.)
